'Treaty' in the Bible

Now Nahash the Ammonite went up and encamped against Jabesh Gilead. All the men of Jabesh said to Nahash, "{Make a treaty with us} and we will serve you."

But Nahash the Ammonite said to them, "On this [condition] {I will make a treaty} with you, by gouging out the right eye of each of you, so that I can make it a disgrace for all Israel."
